How does the new Flight pricing fee works if my guest has multi-city or multiple stop flights?

In case of a multi city booking, the charge will be based on per leg of the booking.

For example: If you booked a ticket from Singapore to Paris with a layover in Doha. Then this journey has two sectors – First from Singapore to Doha and second form Doha to Paris.

In such a scenario, you will be charged 2 USD for this booking, since it involves 2 sectors.
